Imprecise excision of the P-element.
The extent of the deletion in the "cdiT13" mutant chromosome has not been mapped, so it is not known whether the lethality of the "cdiT13" mutant chromosome is due to an affect on cdi or adjacent genes. Mutant embryos do not have obvious CNS defects.
Selected as: flies which have lost the ry+ eye colour marker of the P-element progenitor (P{lacZ}cdi87 or P{FZ}cdi242).
"FBti0009052 == P{lacZ}cdi87" was stated as tentative. "FBti0003444 == P{FZ}cdi242" was stated as tentative.
